HYDRAULIC SAUYSAGE-STUFFING MACHINE.

SPECIFICATION Aforming part of Letters Patent No. 313,556, dated March10, 1885.

Application filed February 2T, 1884.

To all whom t may concern:

Be it known that I, FREDERICK W. TUERK, Jr., a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in HydraulicSausage-Stuffing Machines; and I hereby declare the following to befull, clear, and exact description of the same.

My invention relates to an improvement upon the device patented to meMarch ll, 1884, N o. 294,826.

It is the object of my present invention to avoid the necessity offorming theupper and lower parts of the shell of different relativeproportions, thus permitting it to be cast with a perfectly smooth bore,which greatly facilitates the operation of casting and materiallydiminishes the expense of manufacture. This construction of the shellrenders it possible to employ, without the use of packing, a piston of amuch more desirable form than that shown in my patent above referred to.

My present invention consists in asausagestuffer having a hollow shellcast with a smooth bore, and provided with a piston-head dividing theshell into two chambers, the upper to contain the sausage-meat and thelower to receive the water, by the pressure and discharge of which thepiston is operated, and carrying ahollow piston-rod extending throughthe bottom of the shell, the piston-head having a groove formed upon itscircumference and passages leading from the groove to the interior ofthe piston-rod.

My invention consists, further, in certain details of construction andcombinations of parts, all as hereinafter more fully set forth.

The drawing represents a vertical section'of my improvedsausage-stuffer.

A is the cylindrical shell provided with the ilange t to support thedevice upon the table B, in which an opening is formed to receivethelower portion of the shell, and having openings to admit the bolt sand rod r, operating the three-way cock, by means of which bolt and rodthe device is secured upon the table.

C is the cover hinged upon the shell and adjustably secured thereon bymeans of the swinging eyebolts q. The cover has the openingp andelbow-shaped outlet D, to which the spout (No model.)

ois attached, all as shown and described in my aforesaid patent.

E is a piston-head, preferably cast hollow, as shown, and provided witha tightly-fitting cover, n, carrying the ring n', to afford a hanceivethe hollow metallic piston-rod F, provided with a screw-thread, k',formed upon its circumference toward its upperend to engage with acorresponding screw-thread provided within the central opening in thepiston-head. The bottom G of the shellis irregular in form, as shown,`to afford greater strength of the parts at the juncture of the bottomGand shell A, 4thereby to prevent rupture at this point by the pressureof the water, and to provide a concavity which shall produce a chamberunderneath the piston-head when the latter occupies its lowest positionwithin the shell to receive the water, by the pressure of which thepiston is raised.

To obviate the use of packing, which would otherwise be required toprevent the entrance of water from the chamber underneath the pistoninto the chamber above for the sausagemeat, a groove, t'. is' formedaround the periphery ofthe piston-head to receive any water that mayrise with the motion of the piston,and slanting passages 71 leadingtherefrom through the solid portion e of the piston-head into the hollowportion of the same, having the oblique bottom e2, and into the slantingpassages ci", formed in the hub g of the pistonhead, and leading toapertures f, provided in the hollow piston-rod F at points where thepassages c3 meet the piston-rod, conduct the water iut-o the latter,whence it passes off through thcwaste-pipeH by means of thehoseconnection d, between the latter and the hollow piston-rod. Thepiston-rod F, which extends through the bottom of the shell A, forms notonly a means of exit for water forced between the shell A and iiange mof the pistonhead during the operation of the latter, thus providinglubrication, but it also, owing to its rigidity, being steadied by thenut c, suitably ICO roV

packed, as shown, affords a steady guide for the piston-head.

What I claim as new, and desire to' secure by Letters Patent, is

l. In a sausage-stuffer, the combination, with the shell A, of apiston-head, E, and hollow piston-rod F, extending through the bottom ofthe shell, the said piston-head having a groove formed upon itscircumference, and passages leading from the said groove to the interiorof the piston-rod, substantially as described, and for the purpose setforth.

` 2. In a sausage stui'er, the combination, with the shell A, of ahollow piston-head, E, provided with a cover, n, and having a groove,t', formed upon its circumference,and passages h, which lead into thehollow portion of the piston head and into openings e3 in the hub g, anda hollow piston-rod, F, extending through the bottom of the shell, andprovided with openings f, substantially as described, and for thepurpose set forth.

3. In a sausage-stuffer, the combination,

with the shell A, having the iiange t, o f a hollow piston-head, E,provided with a cover, n,

and having a groove, fi, formed upon its cir- A cumference, and obliquepassages h, leading into the hollowportion of the piston-head providedwith an oblique bottom, e2, and into 0blique passages e3 in the hub g',and a hollow piston-rod, F, extending through the bottom of the shell,and provided with openings f, registering with the passages 6*,substantially as described, and for the purpose set forth.

4. A sausage-stuer, comprising in combination the following elements,viz: a shell, A, having the hinged cover C adj ustably secured upon thesaid shell by means of swinging eyebolts g, and provided with theelbow-shaped outlet D, and means for adjusting a spout, o, thereon,hollow piston head E, provided with a cover, n, and having agroove, i,formed upon its periphery, oblique passages h, leading into the hollowportion of the piston-head provided with an oblique bottom, e, and intooblique passages e3 in the hub g, a hollow metallic piston-rod, F,provided with openings f, and passing through the bottom of the shell A,means for admitting and releasing the medium for operating thepiston-head, and a tube, d, connecting the piston-rod F anddischargetube H, all being constructed and arranged to operatesubstantially as described.
